是一种测量中低温度的现场检测仪表。 Bimetal thermometer is a kind of on-site detection instrument for measuring low and medium temperature. It can directly measure the temperature of liquid vapor and gas medium in the range of -80 ℃-+ 500 ℃ in various production processes.
Display temperature on site, intuitive and convenient
Safe and reliable, long service life;
Pull-type thermometer can be maintained or replaced for a short time without stopping the machine.
分为：轴向型、径向型、135º型、万向型等品种齐全，适应于各种现场安装的需要。 The bimetal thermometer is divided into: axial type, radial type, 135º type, universal type and other varieties, which are suitable for various site installation needs.
